This is a bush we have in most of the gardens along my street. One of the less civilised Hypericums (aka St John's Wort), it's scruffy and self seeds fairly easily. No one has grubbed it out and replaced it with an "official" plant from a Garden Centre and if I ever upgrade this blog to scratch'n'sniff you'll understand why.
When it's sunny, the whole plant (not just the flowers) has a gorgeous and powerful scent. Think warm treacle, tobacco and rubber.
You'll sometimes see me leaning over garden walls and sniffing furtively at other people's tidy Hypericums. I'm just checking they haven't caught up with our variety :-)
